Description
Technical field
The present invention relates to pesticides application technical field, specifically a kind of sterilization synergy group for being applied to preventing and treating tomato virus disease
Compound.
Background technology
Moroxydine Hydrochloride (moroxydine hydrochloride) chemical name：N-N- (2- guanidine radicals-second imido
Base)-morpholine hydrochloride is a kind of wide spectrum, hypovirus control agent.Decoction after dilution is sprayed application to after plant leaf surface, and medicament can
Entered by aqueous vapor hole in plant, suppress or destroy the formation of nucleic acid and lipoprotein, prevented the reproduction process of virus, play anti-
Control the effect of virus.
Asarum, alias：The careless asarum of asarum sieboldii, basin, Kingdonia uniflora, beautiful fragrant silk, golden basin grass etc., Latin literary fame：Asarum
sieboldii Miq.Belong to Aristolochiaceae, herbaceos perennial is conventional Chinese medicine,《Sheng Nong's herbal classic》It is classified as top grade.
This kind of all herbal medicine.HERBA ASARI from Liaoning of China root is thin, color sallow, leaf color are green, pungent peppery numb tongue.It is warm-natured, it is slightly poisonous.The thoughts of returning home, lung, kidney channel.Have
Wind-dispelling, cold dispelling, warm lung, water-filling, the effect having one's ideas straightened out.In addition, asarum also have anti inflammatory immunity, local anaesthesia, improve metabolism,
Antibacterial action, also available for Chemotherapy of Tumor Patients and the Neuroleptic Leukocytopenia of caused by radiation.Show Herba Asari extract through experimental study
There is certain In-vitro Inhibitory Effect to gram positive bacteria, hay bacillus and typhoid bacillus, to a variety of fungies such as Aspergillus flavus, black song
Mould, Candida albicans etc. have inhibitory action.
Tomato virus disease is the very important disease of a class in tomato production, has generation throughout the country, especially with the autumn
Tomato is aggrieved heavier, the incidence of disease 10%~30%, and 50%~70% is up to when serious, up to 100% when most heavy, production loss compared with
Greatly, tomato cultivation is constituted a serious threat.In the real process of agricultural production, controlling disease is easiest to generate the problem that disease
Evil is drug-fast to be produced.Different cultivars composition is compounded, and is to prevent and treat resistance disease very common method.Heterogeneity is answered
Match somebody with somebody, according to practical application effect, to judge that certain compounding is synergy, addition or antagonism.Study, find by inventor
Herba Asari extract is mutually compounded with Moroxydine Hydrochloride, there is good synergistic effect within the specific limits.And Herba Asari extract with
Moroxydine Hydrochloride correlation compounding, at present at home and abroad there is not yet relevant report.
The content of the invention
It is good that the technical problem to be solved in the present invention is to provide a kind of preventive effect, and the germ resistance to the action of a drug can be delayed to produce, and crop is pacified
The full sterilization synergistic composition for being applied to preventing and treating tomato virus disease.
The present invention is to be achieved through the following technical solutions：A kind of sterilization synergistic combination for being applied to preventing and treating tomato virus disease
Thing, active ingredient is made up of Herba Asari extract and Moroxydine Hydrochloride, and the weight ratio of Herba Asari extract and Moroxydine Hydrochloride is 10-1:
1-10.Preferably, the weight ratio of Herba Asari extract and Moroxydine Hydrochloride is 3-1:1-7.
Described its active ingredient of sterilization synergistic composition accounts for the 1-40% of sterilization synergistic composition gross weight, and surplus is agriculture
Acceptable auxiliary element on medicine.
Described bactericidal composition adds what corresponding auxiliary element was made according to method known in those skilled in the art
Formulation is wettable powder or water dispersible granules.
The auxiliary element that uses of present invention sterilization synergistic composition includes dispersant, wetting agent, disintegrant, binding agent, filled out
Material etc. or it is other be beneficial to the known substance that active ingredient is stablized in the formulation and drug effect is played, be all in field of pesticide preparation often
With or allow the various composition that uses.
The Herba Asari extract is prepared from by the following method：Asarum herb is cleaned, dried, is crushed with pulverizer, mistake
40-60 mesh sieves, obtain crushed material；7-10 times is added in the crushed material of gained and measures 95% ethanol, is stored at room temperature mistake after extracting 3-5 days
Filter, obtains leaching liquor；Filter residue adds 7-10 times and measures 95% alcohol steep again, extracts again as stated above 1 time；Merging is extracted twice
Liquid, powder is freeze-dried to obtain after being then concentrated under reduced pressure into the medicinal extract that relative density is 1.15-1.20 with Rotary Evaporators, that is, is made
Herba Asari extract.
Beneficial effect of the present invention：The bactericidal composition that the present invention is compounded by Herba Asari extract and Moroxydine Hydrochloride is used
In preventing and treating tomato virus disease, its obvious synergy is good to tomato virus disease prevention effect, and can induce and strengthen plant
Immunity, so as to suppress infecting for virus.In addition, the composition of the present invention can reduce resistance risk and delay the germ resistance to the action of a drug
Produce, low-residual, to crop safety, with wide market application foreground.
Embodiment
Technical scheme and technique effect are described further below in conjunction with specific embodiment, institute of the present invention
The percentage stated is weight percentage.
The Herba Asari extract is prepared from by the following method：Asarum herb is cleaned, dried, is crushed with pulverizer, mistake
40 mesh sieves, obtain crushed material；9 times of 95% ethanol of amount are added in the crushed material of gained, filters, must soak after being stored at room temperature extraction 5 days
Extract；Filter residue adds 7 times of 95% alcohol steeps of amount again, extracts again as stated above 1 time；Merge leaching liquor, Ran Houyong twice
Rotary Evaporators are freeze-dried to obtain powder after being concentrated under reduced pressure into the medicinal extract that relative density is 1.20, that is, Herba Asari extract is made.
First, Toxicity Determination is tested
Test method：Indoor pot tobacco susceptible variety plant is mixed to the 4-5 leaf phases with the decoction of different ratio various concentrations
Isometric viral juice frictional inoculation is closed, 3 plants are often handled, 3 leaves of often selecting good strains in the field for seed are repeated 4 times, withered spot number is investigated after 3-4 days, meter
Calculate inhibiting rate.Inhibiting rate is converted into probit value (y), liquor strength (μ g/mL) is converted into logarithm value (x), with least square method
Virulence regression equation (y=a+bx) is tried to achieve, and thus calculates the EC of every kind of medicament50Value.Simultaneously according to the common poison of the abundant methods of Sun Yun
Y-factor method Y (CTC) evaluates the synergistic effect of pharmacy mix, i.e. CTC≤80, and composition shows as antagonism, when 80<CTC<
120, composition shows as summation action, and when CTC >=120, composition shows as synergistic effect.Result of the test such as table 1.
